Figure 16 is a view partly in section and partly in elevation taken on line 1616, Figpressurecylinder rigidly mounted on the underframe of the car and a system of connected rods and levers for transmittingforce from the cylinder to brake shoes which cooperate with the wheels of the car. The brake shoes are mounted on brake beams and the latter are pivotally connected to and actuated by the brake levers which, as is 'knownfare inclined at an angle of approximately forty degrees to the vertical. One of these brake levers, namely, the one to which the brake applying force is first transmitted from the brake ,cylinder,is commonly called the'live lever while the other brake lever, namely, the one anchored to some part of the car, is commonly termed the dead lever. tion only relates to the means for connecting or anchoring the dead lever to the car only a portion of the brake rigging has been illustrated, namely, the dead lever, designated by the referencenumeral 1 and a portion of the push rod, designated by the reference numeral 2, which connects the bottom portionsof the live and dead levers. The brake beam to which the dead lever is pivotally connected by a pin 3'is also illustrated and it is designated by the reference numeral 4.

The means for attaching or anchoring the end of the dead lever to the car underframe illustrated-in Figures 1 to 13, inclusive, comprises a tension connector involving a rotatably mounted member carried by the under- .frame and rigid means pivotally connected at one end to the upper end of the dead lever and pivotally connected at the other end to the rotatably mounted member. The rotatable member, designated by the reference numeral 5, is carried by a bracket 6 rigid with the underfr'ame and is of substantially U-shape having horizontally spaced vertically disposed arms 7 connected by an arcuate portion 8. The bracket 6 may be advantageously formed as an integral casting and is provided with atop portion having, longitudinally spaced pad portions 9 each of which is adapted to receive a rivet 10 for rigidly securing the bracketto a bottom flange 11 'of one of the center .sill members 12 of the underframe. The bracket is also formed withupper and'lower jaw=members 13' and 14:, respectively, spaced below the top portion thereof andfinte'grally connected thereto by web portions 15 and 16, respectively, which extend downwardly from the inner ends of the respective pad portions 9; The web 15 terminates adjacent the lowerj'aw member 14: and integrally connectsthe inner ends ofboth jaws while the web portion 16 terminates ad As the invenv bracket. I

j acent the outer edge of the upper jaw. The web 16 and the portion of the web 15 intermediate the top portion of the bracket and the upper jaw member converge downwardly toward the upper aw and are connected by a longitudinally extending, preferably centrally disposed, plate portion 17, the upper edge of which is provided with a substantially horizontal rigidifying flange 18 spaced slightly below the pad portions 9. The bracket may be conveniently reinforced by two pairs of oppositely projecting flanges 19 and 20,

respectively, the flanges 19 extending between the web 16 and the adjacent pad portion and the flanges 20 extending between the web '15 and the pad portion adjacent the latter. If desired, the flanges20 may extend, as at 21, beneath the lower aw member 14 to adjacent the outeredge thereof. t

The jaw members of the bracket are preferably connected bya substantially vertical post or member 22 which is adapted to be embraced by the U-shaped rotatable member 5 and serve as an anchorage for the latter. The

post isprovided with a cylindrically curved surface affording a bearing for the inner surface of the arcuate portion 8 of the rotatable member and both of these surfaces are preferably of substantially the'same radii.

- By forming the surfaces in this manner it .will be observed that an extended bearing area is provided for the rotatable member and in order that the latter will have the same bearing area in substantiallyall operative positions it may assume, the cylindrical surface of the post isgreater than one hundred and eighty degrees in extent. However, since the distance between the arms 7 of the rotatable member is less than twice the radius of the cylindrical surface, thepost'is formed with a fiat side or portion 23 so that the thicknessof the post longitudinally of the bracket will be somewhat'less than the distance between the arms. With this construction the rotatable member may be easily applied to or removed from the bracket by arranging it at substantially right angles to its normal position. The flat portion of the post is preferably recessed'as at 24 so as to reduce the cross sectional area of the post and thereby minimize the possibility of shrinkage cracks'during the casting operation of the To eliminate the necessity of machining the cooperating faces of the cylindrical portion of the post and the arcuate f portion of the rotatable member and yet to insure bearing contact at vertically spaced points between these surfaces and preferably at points adjacent the upper and lower edges of the rotatable member, the arcuate member 26 may be advantageously of U-shape mal operation of the dead lever. The arms are spaced a-suificient distance apart to re-v ceive the upper end of the lever and are pivotally connectedthereto by a pin 29,'the pivotal axis of which is substantially perpendicular to the plane of normal operation of the lever.

In order that the arms and lever may be connected in various positions of adjustment to take up slack in the brake rigging, the arms are provided with a plurality of pairs of registering apertures 30, any pair of which is adapted to receive the connecting pin 29.

The other member, 27, of the rigid means is of substantially I-shape in cross section and is formed with angularly disposed end portions 31 and 32. The end portion 31 is sub stantially vertical and is interposed between the arms 7 of the rotatable member 5, being pivotally connected theretoby a pin 33 whose axisis substantially horizontal. The portion 32 is disposed in a plane substantially parallel with the plane of the dead lever and is inter posed between the arms 28 of the member 26, being connected to the latter by a pin 34. The portion 32 of the member 27 is integrally formed withlaterally extending oppositely projecting lugs 35, one of which is'disposed in over-lapping relation to thelower edge of one of the arms of member'26 and the other of which is disposed in overlapping relation to theupperedge of the other arm thereof. It will thus be observed that the members 26 an'd27 are immovably connected, the pin 34 serving to prevent relative. longitudinal.

movement thereof and the lugs 35, together with pin 34, serving to prevent relative angular movement.

From the foregoing it will be observed that the rigid means is connected atone end by the pivot pin 29 to the dead lever and is connected at the other end bythe pivot pin 33 to the rotatable member and the axes of these pins are disposed at angles to each other. Moreover, the axis of the rotatable member is substantially vertical and at right angles to the axis of the pivot pin 33. The rigid means is therefore pivotally connected to the dead lever and universally connected to the racket. Thus the lever is connected to the underframe of the car in such manner that it may move angularly with respect to the longitudinal axis of the underframe in sub.-

stantially all directions to compensate for 7 relative movement between the'car truck and car body. 7

In the form of the invention illustrated in Figures 14 to 17, inclusive, the tension'connector comprises a rota-table member'36 and a rigid member 37. The rotatable member is mounted upon a bracket, 38 rigid withthe advantageously be formed as an integral casting having a top portion 40 for attachment by rivets 41 to the bottom flange 11 of the center sill 12 and a downwardly and outwardly extending box-shaped portion 42. The upper end of the box portion is preferably open so that the bracket may be'conveniently cast and the top portion40 of-the latter maybeconveniently reinforced along its outer marginaledge by substantially verof rotation of the'member 36'is preferably plane of normaloperation 1 parallel with'the of. the dead lever.

The rigid member 37 of the tension connector is provided adjacent one end with spaced arms 46 between which the upper end of the dead lever is adapted to be disposed and with 1 a portion 47 adjacent its other'end adapted to be interposed betweenthe arms 39 of the r0- tatable member. The rigid member may be conveniently formed from two similarly shaped members which maybe connected together by a rivet 48 so as to provide the spaced arms 46 and the portion 47. Pivot pins 49 and 50 whose axes are substantially normal to the planeof operation of the dead lever are preferably employed for respectively connecting the rigid member. to the dead lever and rotatable member. The arms 46 of the rigid member are preferably formed with a plurality of pairs of apertures 51 for receiving the pin 49 so that the rigid member and dead lever may be connected in various positions of ad ustment to take .up slack in,

the brake rigging.

From the foregoing it will be observed that the rigid member 36 is universally connected to the bracket 38 by the rotatable member 36and is'pivotally'connected to the dead lever. Thus the lever is capable of moving angularly with respect to the longitudinal axis of the underframe in substantially all directions to "compensate for relative movementbetween the car truck and the car body.
